What should be avoided for the best draft beer service?

1. Short taps

2. Using ice to cool the beer

3. Compressed air as a gas source

4. Storing beer in a basement

The correct answer is: Compressed air as a gas source

Using compressed air as a gas source for dispensing draft beer is indeed something that should be avoided for optimal service. This is because compressed air can introduce oxygen into the beer system, which can lead to oxidation and spoilage of the beer. Oxygen exposure can negatively affect the beer's flavor and stability, resulting in off-flavors and a diminished overall quality. In draft beer service, it is essential to use a proper gas source, such as CO2 (carbon dioxide), which maintains the beer's integrity and helps retain its carbonation without compromising flavor. CO2 is inert and preserves the beer’s characteristics while aiding in proper pouring and maintaining the appropriate serving pressure. Regarding the other options, while short taps, using ice to cool the beer, and storing beer in a basement may have their own considerations, they do not fundamentally compromise the beer's integrity in the same way that compressed air does.
